Definitions

  • the invention relates to a spinning roller for drafting systems for thread production with a cylindrical roller body, with one arranged on the roller body, with it a plain bearing forming, axially fixed cylindrical sleeve from for Dry running suitable plastic and with a on the cylindrical Sleeve applied elastomeric covering.
  • Such a spinning roller is in DE-U-18 21 235 as a pressure roller described for drafting systems, in which than usual Roller covering leather and rubber can be called.
  • US-A-3 785 022 describes a textile processing unit with a central shaft on which a sleeve-shaped core is pressed out of a hard rigid tube from a thermoplastic material such as acrylonitrile butadiene styrene, Polypropylene, nylon or polycarbonate with a Rockwell hardness of 95, including hard rubber or phenol formaldehyde are mentioned.
  • This sleeve core sits on the press fit the central wave.
  • a rubber element is placed around the core applied that separately on an extruder can be formed. The rubber element is using expanded elastically by air, guided over the core sleeve and then by interrupting air expansion contracted so that it is tight to the core sleeve docks around.
  • the arrangement thus formed is still with a Textile strips wrapped and then at 150 ° C for 90 minutes hardened and ground after cooling. Instead of applying the soft rubber hose by widening it with With the help of air, several layers can also be laminated on will.
  • the arrangement is a rigid unit that shows no bearing. A material connection between the core sleeve and the rubber element is not recognizable.
  • the object underlying the invention is that Modify spinning roller of the type mentioned in such a way that it can be manufactured extremely simply and inexpensively.
  • This task is based on the spinning roller of the beginning mentioned type solved in that the plastic of the cylindrical Sleeve made of a high temperature resistant polymer material exists and that the elastomeric coating on the cylindrical Sleeve directly by extrusion, preferably cross-head extrusion or injection molding, applied and vulcanized connected to it.
  • the cylindrical sleeve consists of a piece of pipe a high-temperature resistant, vulcanizable, for dry running suitable polymer material, which is expedient is electrically conductive.
  • the threads that can be produced with the spinning roller according to the invention include filaments as well as short and long staple fibers.
  • the Spinning roller is used in ring spinning except for drafting systems also for OE spinning, jet and airjet spinning, for special processes, such as RingCan, Plyfil, Dref etc. as well as in spinning preparation, namely in combing machines, flyers and the like, applicable.
  • Thermoplastic can be found as a plastic or plastic compound Materials based on polytetrafluoroethylene homopolymer (PTFE), tetrafluoroethylene-perfluoropropylene copolymer (FEP), polyether ether ketone (PEEK), polyimide, polyphenylene sulfide (PPS) or blends thereof in compounds with e.g. Molybdenum disulfide, graphite, bronze, filler or fiber reinforced Use.
  • PTFE polytetrafluoroethylene homopolymer
  • FEP tetrafluoroethylene-perfluoropropylene copolymer
  • PEEK polyether ether ketone
  • PPS polyimide
  • PPS polyphenylene sulfide
  • blends thereof in compounds with e.g. Molybdenum disulfide, graphite, bronze, filler or fiber reinforced Use.
  • the elastomer covering preferably consists of a special compound based on an acrylonitrile-butadiene copolymer (NBR rubber) with an acrylonitrile content of 18 to 50% a partially or fully hydrogenated acrylonitrile-butadiene copolymer (H-NBR rubber) or from a carboxylated acrylonitrile butadiene terpolymer (X-NBR rubber) with a carboxyl group content from 1 to 9% or based on EPDM rubber.
  • NBR rubber acrylonitrile-butadiene copolymer
  • H-NBR rubber partially or fully hydrogenated acrylonitrile-butadiene copolymer
  • X-NBR rubber carboxylated acrylonitrile butadiene terpolymer
  • the manufacturing cost is further simplified in that the formation of the plain bearing bushing of the elastomer covering extrude simultaneously with the cylindrical sleeve and can be vulcanized, creating a firm connection between Elastomer covering and cylindrical sleeve is reached.
  • the axially in the appropriate distance Pipe pieces are separated, each of which is a plain bearing bush that forms the inner cylindrical sleeve and the outer Covering.
  • the assembly is then extremely simple since the slide bearing bushing thus obtained only on the roller body, with which it forms the plain bearing, attached and axially needs to be fixed.
  • the outer diameter of the elastomer covering can be relatively small if this allows the length of the fiber to be spun, or the wall thickness of the elastomer covering can be significantly enlarge, especially with soft covers with ⁇ 70 ShA improves the usage properties and the service life increased, since more frequent regrinding is possible.
  • the spinning roller shown in the drawing has a cylindrical one Roller body 1 with a central section 2 for the Inclusion of a pendulum arm, not shown. On both sides this central section 2 is on the roller body 1 each a slide bearing bush 3 plugged in and axially fixed.
  • the plain bearing bush 3 consists of a cylindrical Sleeve 4, on which an elastomer coating 5 is applied.
  • the cylindrical sleeve 4 consists of a high temperature resistant, polymer suitable for dry running, which with the elastomer coating 5 is connected by vulcanization.
  • the axial Fixing the plain bearing bushes 3 on the associated sections of the roller body 1 consists of an annular shoulder 6a and a circlip engaging in a circumferential groove 6b.
  • the ring shoulder 6a is 1/10 mm in Provide outer diameter smaller than the outer diameter the respective cylindrical sleeve 4.
